APPARATUS FOR THE REMOVAL F Application led March 6, 1923. Serial No. 623,213.

To all whom t may concern-f Be it known that I, MARIO SoHIEsARI, a citizen of the United States, residin in the city of New York, county and tate e of New York, have invented certain new and useful Improvements in Apparatus for the Removal of Snow, of which the following is a full, clear, and exact description, reference being had to the accompanying l0 drawings, forming a part of this specilication. A

This invention relates to apparatus 4for the removal'of snow from streets and other thoroughfares where water and sewers are available, and more particularly refers to improvements over apparatus for the same purpose vdescribed and claimed by me in a co-pending applica-tion entitled Method of and apparatus or'removing snow, vliled by me von October 28, 1922, ySerial No. 603,880.

.The main object of this rinvention is to provide a novel and improved arrangement of the snow receivingI chamber in devices such as described in the above-entitled application, wherebyv the disposal of the snow collectedV may be effected in a more rapid and ellicient manner.

A further object is to provide a novel arrangement of discharging means for said chamber, whereby a quick discharge of the snow will be facilitated, 'and the possibility of clogging of the outlets considerably lessened. Y

Other objects will more fully appear as the description proceeds, and willbe pointed out and claimed in the appended claims.

In the co-pending. application above referred to, I described various types of devices whereby the snow may be collected 40 and directed or fed in the path of a stream of vwater under pressure, for which an exhaust conduit, conveniently placed in relation to the line of travel of said water, is provided.

In some of the devices shown, mechanical means for effecting a fractional and gradlual feeding of the snow in the path of a stream of `water issuing Jfrom a nozzle, have been illustrated, while in others no such 0 means have been provided, the snow being fed to the water in bulk.

The chamber proper, where the snow is actually directed for ultimate disposal, is

however constituted by a single receptacle Within which the stream issuing from the tion is to eliminate as 'far as possible such 'a condition, and to insure a speedy and efiicient operation of the device, by a cellular constructionof the snow chamber, a 'corre- 70 sponding subdivision of the stream of water in a number of elementary streams fed by individual nozzles into 'said cells, and individual outlets for each cell, leading toa main collector; or, in other words, by subdividing the mass of snow which is fed to the chamber, by exerting the action of the water on the same simultaneously at a number of points, and by accordingly multiplying the ypoints of outlet.

In this manner, a mass of snow is attacked by the water simultaneously at various points. and is more rapidly dissolved and carried away; said action of the water being further facilitated by the fractioning of the snow which has previously taken place, and by the possibility of the discharge being eli'ected simultaneously at various points. Y

In the drawings, which are intended Jfor illustrative purposes only, and not in a limiting sense, I show a typical arrangement of device embodying my invention; and in the same,

Fig. l is a Jfront view in elevation, partly i .sectioned and broken away, of a device of the hand operated type;

Fig. 2 is a side view in elevation of the same, partly sectioned and broken away;

Fig. 3 is a detail view in perspective of a blade-like valve Jfor the snow chamber; and, Fig. 4 is a View in perspective of a street in which two of the devices illustrated are shown in simultaneous operation. The device illustrated, consists of a funnel shaped shovel or scoop 10 provided with a handle 11, by means `of which the same may be propelled on the pavement, collect- 'ing snow as it proceeds. The rear part 12 of the scoop, which constitutes the Snow chamber proper, is subdivided in a plurality of elementary chambers or cells 13, by partitions 14 running from fronti to rear.

15 designates a crosswise running water distributor which may be connected to a street hydrant by means of flexible conduitV ing to a common collector 19 to which may .gio

beattached a flexible conduit 20 -directing the water and snow to the sewer.

Said collector 19 is provided with a shoe 20, supporting the weight of the saine, and enabling the device to slide easily on the ground. p

The quantity of snow against which each elementary stream is directed being small, the discharge of the same will easily take place without clogging of outlets, and without water overflowing from the front of the scoop. The snow chamber however, may

preferably be physically divided from thev front part of the scoopby a blade valve 21, pivoted at 22, and provided with notches 23 vcorresponding-to partitions 14, so that whenever a partial clogging shouldnevertheless take place, the snow chamber may be closed, and water prevented from overflowing.

`'Iothis end, shaft 24, on which blade valve 21 is mounted, is providedl at each end with a cam shoe 25, whichinaintains blade valve 21 open when the device is propelledforward, and Jwill close it if the devi-ce is l moved backward; in such case the blade valve assuming the position shown in Fig. 2.

In such a position, the full pressure of the water will be exerted against the snow obstructing the passage and this will ordinarily be sufficient to gradually force it through the outlet, clearing the same. v

In Fig. 4 it is shown how a plurality of devices may be connected forsiinultaneous operation to a common supply tube 26 attached to a hydrant 27, and to a common discharge tube 28, leading to a sewer opening 29. Y Y

The handle 11 has an inverted U shape, so that the device may be operated by either one or two men, according to the depth and consistency ofthe snow.

A similar sectional arrangement of the snow chamber may of course be adopted, together with the multiple nozzle feed and multiple discharge, in connection with def vices of design other than the one shown, and in connection with devices operated by power or by animal traction. Various Vtypes of suoli devices have been illustrated and described in the vco-peiiding application above referred to, and no more than reference to the saine is therefore considered necessary. Y

It may be notedthat some of the devices referred to are provided with mechanical feeding means directing or discharging Vthe vr snow in a snow chamber which is closed instead of open as in therdevice described herein 5' and it is obvious that the same principle of Y cellular construction and multiple distribution and discharge can equally well 'be applied in'such devices.
